I have a feeding ring in Marina's tank since I feed her micropellets (helps her so she doesn't have to chase the food around). She has began leaping into her ring. She started out swimming underneath it to get the food. She now gets beside the ring and jumps out of the water to get into the center of the ring. It scared me the first time she did it - and she switches up which side she jumps from. I thought it was so cute - maybe it's just the cheesy fish mommy in me lol.
